Particle contamination can be a significant problem in semiconductor manufacturing.
factoring (plural factorings)
1A financial transaction whereby a business sells its accounts receivable to a third party (called a factor) at a discount.
2(mathematics) The process of factorization.
Factoring can refer to the following:
•Factoring (finance), a form of commercial finance
•Factorization, a mathematical concept
•Decomposition (computer science)
•A rule in resolution theorem proving, see Resolution (logic)#Factoring
In computer programming and software design, code refactoring is the process of restructuring existing computer code—changing the factoring—without changing its external behavior.

Quantum dots (QDs) are used for advanced virus labeling, especially for real-time single-virus tracking, with Wuhan-based research at the Chinese Academy of Sciences (Wuhan Institute of Virology) developing methods to attach QDs to viruses like influenza (H1N1) or package them inside for tracking infection, enabling detailed study of viral entry and mechanisms by exploiting their bright, stable fluorescence, though challenges remain in avoiding alteration of viral function.
Who excited the quantum dot?
Methods involve biotin-streptavidin links to viral envelope lipids
When the wrong sex hormones (specifically, high levels of androgens in a female fetus or insufficient/incorrect hormonal signaling in a male fetus) cross the blood-brain barrier (BBB) during critical, sensitive windows of development, it can lead to permanent, "organizational" changes in brain structure, behavioral, and neurological differences.
The brain is usually protected from maternal estrogen by alpha-fetoprotein, but this does not always protect against androgen exposure.
Here is what happens when this "mismatch" occurs:
1. Permanent Alteration of Brain Sexual Differentiation
The brain undergoes sexual differentiation (masculinization or feminization) in the womb (starting in the second trimester) and in early infancy. If this process is disrupted, the brain's organization may not match the genetic sex or the genital development.
•Excess Prenatal Testosterone (Masculinization): If a female fetus is exposed to high levels of androgen, it can induce male-typical organizational changes in brain structures.
•Androgen Insensitivity (Feminization): In cases of complete androgen insensitivity syndrome (CAIS), XY individuals with high testosterone have female-typical brain structures because the brain cannot process the androgens, leading to female-typical behavior.
2. Behavioral and Developmental Consequences
Studies suggest that prenatal hormone imbalances during critical windows are linked to several, often long-term, behavioral outcomes:
•Play Behavior and Gender Identity: Prenatal androgen exposure in females is associated with increased male-typical play behavior, toy preferences, and higher rates of gender dysphoria.
•Autism Spectrum Conditions (ASC): Research indicates that elevated prenatal testosterone is a potential risk factor for autism spectrum conditions, which are more common in males.
•Cognitive and Emotional Differences: Incorrect hormonal exposure can lead to changes in fine motor skills, spatial tasks, and verbal memory.
3. Structural and Functional Brain Changes
The "wrong" hormones can change how brain regions develop:
•Amygdala and Prefrontal Cortex: These regions, involved in emotion regulation, are heavily influenced by early hormone exposure. Improper exposure can lead to reduced volume or altered connectivity.
•Hippocampus: Changes here can affect memory and cognitive function.
•White Matter Anomalies:Studies onCongenital Adrenal Hyperplasia (CAH), where females are exposed to high prenatal androgens, show white matter anomalies, indicating potential differences in structural connectivity.
4. Long-term Mental Health Risks
The organizational changes caused by these hormonal mismatches can heighten susceptibility to psychiatric conditions in later life:
•Neuropsychiatric Disorders:Abnormal hormonal exposure in adolescence (a second sensitive window) can affect neurotransmission, particularly the dopamine system, increasing the risk of schizophrenia, depression, and anxiety.
•Emotional Dysregulation:Atrophy in specific regions, caused by hormonal imbalances, is linked to difficulty in controlling negative emotions, increased irritability, and depression.
In essence, the brain becomes "mis-sexed" relative to the rest of the body, leading to structural differences in regions like the hypothalamus and limbic system that are resistant to change later in life
